Actually, every country outsources intelligence-gathering. The USSR "outsourced" their gathering of intelligence to John Walker, Jerry Whitworth, Jack Dunlap, Aldrich Ames, Robert Hansen, Julius & Ethel Rosenberg, et cetera, and so on, and so forth...
"Intelligence gathering" is understood to be "outsourced" as you put it, but this is not my real concern here.
My concern is foreign nationals on the payroll who do much more than simple intelligence gathering. Situations where we are forced to have foreigners having direct access to sensitive information.
You will find very few American citizens working as translators - it is not because we dont have citizens to do the work, we have but our government prefers to hire those outside the US.
You might find it surprising that we are recruiting translators in Saudi Arabia and Pakistan now among other countries and offering these people a fast track to citizenship.
